I recently purchased a pair of Cutom 1s and had to return them after 3 weeks. I was very happy with the sound, it was clear and bright which is what I need becasue of a high end hearing loss.Unfortunately I found them uncomfortable. I didn't like the over the ear design and I had some problems with the fit. I used all the different tips but I was continually loosing sound in one ear or the other when I moved my jaw in a certain way or in some cases just moving my head. I purchased a pair of PK3's which had recieved good reviews from several sources but apon listening to them, they sound muddy in comparison to the Customs. I see the S4s are due out soon. Do they have the same over the ear design, do they compare favorably with the customs in the clarity of their high end? Thanks
